How to recover access to account when no receive verification mail

I would like to login to my account, but i did not receive the verification mail.
I check the mail server : there is no mail receive from gitlab (inbox or spam)

I try to connect on different day, but there is no verification mail.
On start on march, i succeed to get mail from gitlab when i set SSH keys.
But now, i did not receive mail (but the mailbox still work, i receive mail from other sender)

I create a new account to be able to post tis message.

How can i retrieve my first account and the project of this account?

The account where i cannot connect : Olivier · GitLab
My new account to post this message : O Lurik · GitLab

Is it possible to change the mail of the first account?
Is it possible to login without mail verification?

Thank you for any help.
